Silent Warnings (also known as Dark Harvest) is a 2003 science fiction/horror television film about a group of college students who begin finding crop circles by the house they have moved into.

It was commissioned by Syfy (then known as Sci-Fi Channel), written and directed Christian McIntire, and stars Stephen Baldwin, A. J. Buckley and Billy Zane.

[3] After his cousin Joe (Stephen Baldwin) dies, Layne Vassimer (A. J. Buckley) and his girlfriend Macy (Callie De Fabry), along with their friends Stephen (David O'Donnell), Maurice (Ransford Doherty), Iris (Kim Onasch) and Katrina (Michelle Borth), decide to clean up Joe's house with the intention of selling it.

Dread Central panned the film, beginning by comparing it to Signs and remarking that it was more a rip off of Roger Corman’s Carnosaur 2 rip-off of Aliens.

The only differences found between this and Signs is that the farm family of Mel Gibson was replaced by bland teenagers, with a dash of T&A and gore.
